Mitridates was terrified. He replied, however, that the boy was his own son, and that his mother was still living at home, in the hut where they all resided. There seems to have been something, however, in his appearance and manner, while making these assertions, which led Astyages not to believe what he said. He was convinced that there was some unexplained mystery in respect to the origin of the boy, which the herdsman was willfully withholding. He assumed a displeased and threatening air, and ordered in his guards to take Mitridates into custody. The terrified herdsman then said that he would explain all, and he accordingly related honestly the whole story. Astyages was greatly rejoiced to find that the child was alive. One would suppose it to be almost inconsistent with this feeling that he should be angry with Harpagus for not having destroyed it. It would seem, in fact, that Harpagus was not amenable to serious censure, in any view of the subject, for he had taken what he had a right to consider very effectual measures for carrying the orders of the king into faithful execution. But Astyages seems to have been one of those inhuman monsters which the possession and long-continued exercise of despotic power have so often made, who take a calm, quiet, and deliberate satisfaction in torturing to death any wretched victim whom they can have any pretext for destroying, especially if they can invent some new means of torment to give a fresh piquancy to their pleasure. These monsters do not act from passion. Men are sometimes inclined to palliate great cruelties and crimes which are perpetrated under the influence of sudden anger, or from the terrible impulse of those impetuous and uncontrollable emotions of the human soul which, when once excited, seem to make men insane; but the crimes of a tyrant are not of this kind. They are the calm, deliberate, and sometimes carefully economized gratifications of a nature essentially malign. When, therefore, Astyages learned that Harpagus had failed of literally obeying his command to destroy, with his own hand, the infant which had been given him, although he was pleased with the consequences which had resulted from it, he immediately perceived that there was another pleasure besides that he was to derive from the transaction, namely, that of gratifying his own imperious and ungovernable will by taking vengeance on him who had failed, even in so slight a degree, of fulfilling its dictates. In a word, he was glad that the child was saved, but he did not consider that that was any reason why he should not have the pleasure of punishing the man who saved him.
